Application filed February 5, 1910. Serial No. 542,234. a

To all whom it may concern: 1

Be it known "that I, Gnoaon BRANDER, a citizen of the United States, residing at Sutherland, in the county of OBrien and State of Iowa, have invented a new and useful Dish-Washing Machine, of which the following is a specification.

The invention relates to improvements in dish washing machines, and is a continuation of a previous application, filed June .14, 1909, Serial No. 502,099, for a similar machine.

The object of the present invention is to improve the construction of dish washing machines, and to provide a simple, inexpensive and efllcient dish washing machine, equipped with a rotary basket for holding the dishes and other articles and having a pump for discharging water upon the contents of the, basket, andequipped with operating mechanism capable'of enabling the pump to be operated either simultaneously with or independently of the basket.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims here to appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a vertical longitudinal sectional view of a dish washing machine, constructed in accordance with this invention. Fig. 2 is a detail sectional view, illustrating the manner of connecting the depending support with the pitman. Fig. 3 is a plan view of the rotary basket-receivin platform. Fig. 4 is a detail perspective view of the pitman. Fig. 5 is a detail perspective view of the pitman support.

'Like numerals of reference designate corresponding parts in all the figures of the drawin 1 designates a casin constructed of sheet metal, or other suita le 'material and designed to be placed upon a stove or other suitable heater for heating the water used for washing dishes and other articles. The casing is divided by a transverse partition 2 into compartments 3 and 4. The compartment 3 constitutes a dish washing chamber and receives a rotary basket 5, which is adapted to hold dishes and other articles to be washed. v

The rotary basket, which may be of any'preferred construction, preferably consists of a horizontal bottom 6 of sheet metal, or other suitable material, and walls of stout wire. The bottom 6 of the basket may be provided with perforations 7 to permit the water sprayed on the dishes by the means hereinafter described, to drain from the basket.

tal cross wires 8, arranged diametrically and extending from a central vertical shaft 9 to the sides or walls ofthe basket about midway between the top and bottom thereof.

horizontalarms receiving the inner ends of the bracing wires, but the latter may be secured to the shaft and to the side walls of the basket in any other desired manner. The wires 8 besides bracing and strengthening the rotary basket serve as supports for holding plates and other dishes in an upright position facing downward, so as to subject them to the action of steam and hot water when the basket is rotated.

The upright portion of the vertical shaft -9 extends through a'bearing 11 of a hinged section 12 of the top of the casing, and the basket is detachably arranged upon a horizontal platform or support 13. The rotary platform or support, which may be constructed of sheet metal, or other suitable material, is preferably provided with a peripheral wall or flange 14, preferably reinforced by a bead 15, containing a strengthening wire 16. The wall-or flange 14 extends upwardly from the support or platform and retains the basket thereon. The rotary support or platform is secured by suitable fastening devices tothe arms of a spider 17, which is providedwith a depending pivot or spindle 18, mounted in a suitable bearing 19 of atransverse bar 20. The bar 20 is arranged u on the bottom of the casing and is suita ly secured to the same. When the basket is removed from the rotary platform-or support, articles too large to be placed in the latter may be arranged directly upon the rotary support for washing. The cover or section 12 of the to of the dish washing cdmpartment or cham er 3. is hinged at its The 65 -basket is also preferably braced by, horizoninner edge at 21 at a point above the partition 2.

The shaft 9 of the basket is equipped at its upper end with a removable crank arm 22, detachably secured to theshaft by a clamping screw 23, which permits the ready removal of the crank arm, when it is debend 28 of a pump rod 29 of a pump, which is arranged in the tank or compartment 4. The-pump consists of a vertical barrel or casing 30, a discharge spout 31 and a plum ger 32, secured to the lower end of the pump rod 29. The pump rod 29, which is adapted -to be reciprocated vertically through a stufling box 33, has its lower terminal por-,

tion 34 threaded for the reception of upper and lower nuts 85 and 36, located above and below the plunger, washers being preferably interposed between the nuts and packing disks 37 and 38 at'the upper and lower faces of the plunger. The plunger may be constructed in any other suitable manner, and it loosely receives the pump rod, which is adapted to turn freel in the plunger for operatmg the rotary asket. The upper end of'the pump rod is equipped with a suitable head or handle 39, and the crank bend 28, which is composed of spaced horizontal portions and a connecting vertical portion, has its vertical portion arranged in an eye or opening 40 of the pitman. The length .of theyertical portion of the crank bend being sufiicient to permit a fulLstroke of the pump rod, which is adapted to be operated independently of the basket. The pump rod, which is raised and lowered to operate the pump, is also adapted to be turned in either direction to reciprocate the pitman and turn the basket to present different portions of its'contents to the pump. The spout 31 is inclined and extends upwardly from the lower portion of the cylinder, and is provided with a horizontal terminal portion 41, extending through the partition and provided with a flared nozzle 41, arranged to discharge hot water and steam upon the basket from the top to the bottom thereof, as indicated in dotted lines in Fig. 1 of the drawing. The tank or compartment 4 is closed at the top by a fixed section 42, and a removable section 43, adapted to afford access to the interior of the tank or compartment 4 for supplying water to the same, or for any other purpose.

The water enters the pump barrel or cas shape and extending around the outer end.

of the section 46 to provide the eye or 0 ening 40 for the reception of a crank'ben of the pump rod. The terminals 48 of the sides of the strap are extended beyond the inner end of the section 46 to formspaced ears, and they receive between them the inner end 49 of the section 45, which is reduced, as clearly shown in Fig. 4 of the drawing, to fit between the ears or terminal portions 48. The two sections of the pitman are hinged together by a transverse bolt 50, which also connects a depending support. 51 to the pitman. The support 51, which is constructed of suitable material, is approximately U-shaped, being in the form of a stirrup, as clearly shown in ,Fig. 5, and it is adaptedto rest lightly upon the to the casing, and it supports the pitman 111 a level position and permits the pump rod to be reciprocated without actuating the pit man. The pump rod is adapted to slide through the eye of the pitman, and the hinge connection between the sections is also provided to facilitate the reciprocation of the pump rod to prevent the latter from binding in the eye of the pit-man. The operator reciprocates the pump rod for discharging the contents of the pump upon the dishes, or other articles placed in the basket, and the basket is adapted to remain stationary aslong as desired by the operator, and it may partially rotate simultaneously with the operation of the pump by simply turning the pump rod.

The water within the tank is allowed to. come to a boil, so that steam and hot water may be discharged upon the dishes contained in the basket. Each machine, especially when designed for large families, restaurants, and the like, will be equipped with a plurality of baskets .in order that one basket may be used for draining and drying dishes while another is in use within the machine. A comparatively small amount of water will thoroughly wash and rinse the dishesafter the latter have been subjected to the action of'hot water and steam for a short time.

In practice the dish Washing machine will be provided with a suitable drain opening 52, and equipped with means for enabling the greasy or dirty water to be drawn off as desired, and the casing may be mounted upon legs of sufficient length to enable the casing to be placed over a gasolene burner or other heating device. for heating the water.
